Hi MatPed.

If I correctly understand what jcl's written elsewhere, the CBI automatically handles reinvestment - but I could certainly have misunderstood. Hopefully jcl can help clarify for your situation.

As to which .pnl file is used, you're talking about the Z systems? Since they check the CBI once per trading day, my assumption is they re-read the .pnl file each time (rather than keeping it open all the time) so they would automatically pick up a new .pnl file. But this is just an assumption - hopefully jcl can clarify this too.

Regards.
